We just got back on Thurs and for the first time had to use our ADR confirmation print-out since the computer didn't have our reservation in it. We went to Teppan Edo the last day and checked in for our 1:00 ADR but our name wasn't in their computer. I pulled out the print out and showed it to them. They entered our info in the computer and we were actually given the next available table for our group size. This is the first time that we have ever had a problem in all the years we have been going. I just took the print out for each day's TS ADR with me and now I am glad I took the time to print them and carry them with me.
